I have a dell r810 with a built in 4 port nic and no other nic ports available. I wan't to setup a pfsense firewall VM which will require nic passthrough. My concern is that to  my understanding that would make the whole card unusable to unraid. Does that mean that if I pass it through and use it on the vm that I won't be able to access the unraid web gui unless I have another nic card. Or will it work like normal and then I can still use the other 3 ports for pfsense?

 

Edit: I guess what I'm asking is there a way to pass through only 2 ports of my 4port nic leaving 2 available to unraid and 2 available to my pfsense vm? They show up as 2 different iommu groups with all four ports having the same device ID.

If they show up as two different IOMMU groups, you should be able to pass a pair of them through. Have you tried it yet?

 

I'd be more concerned if they will work properly in pfsense... (I've been hurt before)

Thanks for the info. Yes they are in 2 separate iommu groups. I haven't tried passing just a pair of them through. I'm not sure how to do just a pair since they all have the same device id.
